The frequency of the emitted radio waves is:

The energy of a photon is given by:

where h is the Planck constant and f is the photon frequency. Using the frequency given by the problem, we can find the energy of each photon of this radiation:
Answer:
hello
Step-by-step explanation:
-3-1=-4
becouse 3+1=4 and we add minus -

15.
3/8 * 24.1 = 9.0375 miles
24.1 - 9.0375 = 15.0625
He still needs to go 15.0625 miles.
16.
4/5 of $80 is $64.
80 - 64 = $16
16/7.75 = 2.064
He needs to work for approximately another 2 hours.
